Product Description

                                                                      PFA ( Perfluoroalkoxy )   PFA Tubing

PFA (commonly known as soluble PTFE). In terms of its properties, this polymer is similar to PTFE. The big difference is that the alkoxy substituents allow the polymer to be melt-processed. It has improved flow, creep resistance, and thermal stability close to or exceeding PTFE.
 

Combining the best of PTFE and FEP, PFA was developed in the late 1960's in response to a need for a resin with chemical and use temperatures closer to PTFE, yet a resin that would retain the conventional melt processability of FEP.

While slightly more expensive, PFA tubing carries a number of improvements over other types of fluoropolymer tubing. The modifier used in PFA resins results in the same maximum use temperature and chemical inertness as PTFE . PFA tubing also has higher working pressures than FEP and PTFE.

And unlike FEP, PFA chemistry lends itself to very low off-gassing, resulting in high purity that's suitable for pharmaceutical, laboratory, and sampling applications; ultra-high purity grades are suitable for semiconductor applications. In very aggressive industrial environments, such as hydrofluoric and nitric acids at 250 F, PFA tubing is preferred and has proven to provide a long service life.

Key Properties

  • Resistant to more chemically aggressive and abrasive environments than FEP and PTFE at high temperatures
  • Suitable for handling live, saturated steam up to 4.5 bars gage pressure
  • Longer continuous tubing lengths available compared to PTFE
  • Available in high and ultra-high purity grades for contamination sensitive semiconductor, pharma, laboratory and environmental markets
  • Use temperature of 500 F (~260 C) equal to PTFE and 50 F higher than FEP
  • Comes in orange and clear colors


Features:
1. Good folding and cracking resistance
2. High mechanical strength, 1.6 times of PTFE or more
3. Outstanding high/low temperature resistance
4. Chemical stability, electrical insulation
5. Self-lubrication, non-sticky
6. Good UV stability
7. Flame retardant, Abrasion resistant
8. FDA compliant grades available

Typical Applications:
1. Chemical tank liners
2. Pump and valve parts
3. Semiconductor components
